This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.

The aim of this study was to design short interventions based on the literature study, which will change the pupils? posture on mathematics and connections between problem-solving in mathematics and everyday life. An experimental group of 17 pupils in fifth grade participated in the study and were educated in everyday mathematics 20 minutes a day during four weeks. The intervention was measured in a pre- and after questionnaire, in order to control the design and discover possible changes in the pupils? posture on mathematics and connections between problems and everyday life.

Background: The use of digital marketing channels during the last years has increased significantly, especially the use of marketing on the Internet. Hence the communication chart of marketing has been redrawn. The technological development has had a major impact on the marketing discipline. The integration of information technology and marketing has resulted in the emergence of a new field, namely e-marketing. Hence the need for further research is desirable.Purpose: The purpose of this study is to examine alternative marketing procedures that a company can apply to increase the digital awareness and manage their customer relationships.Theoretical framework: Theories regarding digital marketing cycle, SEO and customer relationship.Method: This research is based on data collected through a primary semi-structured interview with a company active in the corporate information industry which also provides a RFQ service.

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

In the world of today, crises and crisis situations are inevitable parts of an organization?s everyday life and it is important for the organization to be prepared for these crises. The organization and its employees have to be in a constant state of alert and they should also have an organized plan for what they will do when (not if) the crisis occurs. The charter tour industry has during a long period of time been active in the global market. They serve thousands of travellers every day and it is the responsibility of the companies within the industry to make sure that their customers are safe and that crises can be prevented, or at least be handled.

Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.

Background and problemThe Swedish mobile market is highly competitive despite the oligopoly that currently exists. A short product life cycle together with fads and new innovations puts pressure on the operators to respond to the ever changing environment and to develop and adapt their strategies after it.As a previous study regarding a specific operator?s strategy was cancelled due to the extensive confidentiality surrounding it, an interest was sparked to perform an industry analysis as this is clearly something the actors spend a great deal of time on developing. The launch of the 4G network will offer new opportunities for the operators regarding products services. It may also impact the competition on the overall market.PurposeThe purpose of this thesis is to present a deep analysis of the industry and give the reader a comprehensive picture of existing conditions.

SammandragDenna studie tar upp problematiken vid införande av administrativa stödprojekt vid Uppsala universitet, främst hur motstånd till förändring kan motverkas. Problemet definieras genom frågan: Hur kan Uppsala universitet effektivisera implementeringen av administrativa stödprojekt? Syftet med denna studie är att lyfta fram kritiska framgångsfaktorer vid genomförandet av projekt. Färdigimplementerade administrativa stödprojekt studerades genom personliga intervjuer med projektansvariga och administratörer på institutioner. Upptäckterna analyserades med hjälp av en processorienterad teori baserad på Demingcykeln.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Our starting point has been to examine how a project manager without knowledge of the industry is able to plan a project. And also which difficulties that may arise. A qualitative study was conducted at project managers who worked in the construction industry and events industry. Seven interviews were conducted, four in the construction sector and three in the events industry. Respondents are active as project manager in Värmland and Närkes counties.

People in Sweden and in Europe have been traveling a lot more lately. Because of the economic boom that has been in a lot of countries people do have more money to spend. Sweden and especially Stockholm has lately become a very popular destination. Also big congresses and business meetings like to choose Stockholm for their meetings. The capital as it looks today does not have the capacity to let all those people stay at the hotels at the same time.
